Claims

[Claims for Utility Model Registration] 1. An operating lever is installed at a specific position on a lever with one end as a fulcrum and a crank connected to the other end, and these move in a constant relative manner, thereby utilizing the reciprocating motion of the operating lever. In a pressurizing device that applies pressure to a pressurized object by moving the lever, the pressurizing position is variable by moving the fulcrum, which is provided with means for moving the fulcrum position so that one end of the lever is parallel to the swinging direction of the lever. mechanism. 2. The pressurizing position variable mechanism by moving the fulcrum position according to claim 1, wherein the means for moving the fulcrum position comprises a pinion rotatably attached to the lever and a rack that engages with the pinion and moves back and forth. 3. The means for moving the fulcrum position is comprised of a plurality of connecting rods having rotating pairs attached between one end of the lever lever and the fulcrum, and means pivotally attached to the pairing portions to bend and extend the plurality of connecting rods. The pressurizing position variable mechanism by moving the fulcrum position according to claim 1.
